.NON-BEFILLABLE BOTTLE.

To all whom it may concern.

Be it known that I, LORENZO C. FURCOLO, a citizen vofthe United States, residing at New Haven, in the county of New'Haven and State of Connecticut, have invented a new and useful Non-Refillable Bottle, of which the following is a specification. q This invention relates to 'a non-refillable bottle ofthat type in which the neck is provided with an enlargement for receiving an expansible sto per that is thrust into the bottleis filled so as to thereafter permit the contents to be emptied, when desired, and prevent refilling of the bottle.

The invention has for one of its objects to improveand simplify the construction of devices 0f this character, so as to be comparatively easy and inex ensive to manufacture, and thoroughly relia le and efiicient in use.

A further object of the invention is the provision of a bottle having a portion of its neck enlarged and provided with a stopper made of elastic material so that the same can be thrust into the neck and automatically expand upon reaching the enlarged portion thereof so as to form a seal against the entrance of liquid into the bottle but not preventing the bottle from being initiallyemptied.

Another object of'the invention is the employment of a sim lo and novel form of stopper made of suitab e material, such as rubber,

that snugly fits in the neck of the bottle when the latter is in filling position and automatically unseats when the bottle is tilted to pour out the c'ontentsthereof.

With these objects in view, and others, as will appear as thenature of the invention is better understood, the invention comprises wit thevarious novel featureaof construction and arrangement of parts,- as will be more full described hereinafter, and set forth h particularity in .the claims appended hereto.

In the accompanying drawing, which illus trates one of the embodiments of the invention, Figure 1 is a longitudinal section of the neck of a bottle with the stopper in normal position therein. Fig. 2 is a similar'view' showing the. bottle inverted and the stopper in unseated position. Fig. 3 is a sectional view of the bottle neck with the stopper artially'inserted to illustrate the methor of lacing the stopper.' Fig. 4 is a perspective view of the stopper. A

are indicated throughout by similar characters of reference.

Referring to the drawing, 1 designates the neck of a bottle that is provided with an enlargement 2 for nin a stopper receiving chamber 3. ruptly at the top, so as to produce a shoulder 4, and from this shoulder the enlargement. 3 contracts downwardly into a secondary neck 5 that connects with the body 6 of the bottle. The stopper 7 preferably comprises a body of compressible and expansible material, such, for instance, as rubber, and it is shaped to approximately conform to the shape of the c iamber 3 in the neck of the bottle.- That is to say, the upper. end of the stopper is considerably larger than the lower end and so proportioned that after having once been inserted into the chamber 3 it cannot be readily withdrawn. The enlarged end of the stopper up ermost and presented to the shou der 4, w iile the narrow lower. end extends into the secondary neck 5. When the stopper is in the position shown in Fig 1, a perfect seal is formed so that liquid cannot be poured into the body of the bottle, When'the bottle isinverted, the

stopper is unseated so that the liquid can ass between the stopper on the interior wal of the. chamber 3. To hold the stopper oflthe shoulder 4 so that liquid can pass out through the neck '1, a plurality of spaced lugs 8 are formed on the enlarged ends 9 of the stopper.

It will thus be seen that the outward flow of the contents of the bottle is practically unrestricted when the bottle is inverted, but the filling ofthe bottle is positively prevented when the bottle is in its normal-position.

In order to facilitate the insertion of the stopper, the upper enlarged portion thereof is hollowed out'so that the'comparatively thin remaining portion can be crumpled, as shown in Fig. 3, as the stopper is thrust throughthe cylindrical neck portion 1. When the stopper reaches the enlargement 2, the stopper automatically expands .so that its enlarged upper end will extend outwardly under the shoulder 4 of the enlargement 2. As a further result of making the stopper hollow, the hollowed out part serves as a basin for 001;

.lecting liquid that is poured into the neck of the bottle in an endeavor to refill the latter. The pressure of the liquid collected in the stopper and of that superimposed in the neck causes the relatively thin part of the stopper hef-lforced outwardly into intimate con- This en argelnent expands abi tact with the internal Wall of the chamber 3,

so that a perfect seal is formed.

'noweonside'r to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made ere within the scope of the claims.

What is claimed is 1- -A containing vessel having a neck the GX- terior Walls of Which are bulged laterally to produce an enlargement defining an annular interior stop shoulder disposed at substantially ri ht angles to the longitudinal plane of the neo the side Walls of the neck at said enlargement being curved downwardly and inwardly to produce a contracted portion at the juncture of the neck with the body of the I vessel, and an enpensible inverted frusto l conical stopper l'zaving smoriath continuous side walls curved to conform to the curveture of the interior Walls of the enlargmnent, said stopper having one end thereof provided with a reduced portion the terminal of which extends Within the contracted portion of the neck of the Vessel and spaced from the adjaeent interior walls thereof, the opposite end of the stopper being opening through the top of said stopper and having a plurality of spaced lugs extending vertically from the upper end thereol and disposed flush with the interior and exterior nlls of the stopper .tt said cavity for engage ment with the stop shoulder when the bottle is inverted. I

in testimony that l claim the hvrcgoing as my own, l; have. hereto :rllixed my signature in the presence of two witi'lesses.
